IMPROVEMENT IN DUMPING-CARS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom It may concer-a Be it known that we, GEORGE B. GOODWIN and SAMUEL MoOOeD, of Milwaukee, 1in the county of Milwaukee, and State of Wisconsin, have invented a new and useful Improvement in Mode of Unloading Wagons, Cars, ofte.; and we do hereby dec-larethe following to be a full, clear, and exact description ofthe same, reference being had to the accompanying vdrawings, in which- Figure l isa perspective viewofour invention, showing the cradle in position, and the track continuous.

Figure 2 is a perspective view of our invention, showing' the operation ofthe tilting-cradle.-

Figure 3 is a side elevation of the trame-work of the cradle.

vL ligure 4 is a transverse section through the cradle and truss.

flfigure 5 is a side elevation of truss, to support the segmental. track. l l

This invention relates to a means for unloading grain from wagons, cars, andthe like; and

It consists in a tilting-platibrm, upon which the ear or Yother vehicle is to be placed, and then tilted, until the grain will, by its own gravity, run out through a small gate at the end'of the car.

Though this-inventionis applicable to the unloading of vehicles of all kinds, yet, for convenience, we will only describe its. application to the unloading of railroad-cars, the same principles being involved whether cars or wagons are being unloaded.

A A are parts of an ordinary railroad-track, and

ik, 13,0, and D, are parts of atilting-cradle, made in said track, so that where a car rests upon said cradle, it may be tilted into the position shown in iig. 2, and, by opening a gate, I, in the end ofthe ear, the grainwill, by its own gravity, run out through said gate, and fall into'ahopper, IWI, which conducts it into the elevatorbin or other receptacle. V

The cradle A B O D rests upon Vtruck-wheels E F,

and these latter tra-vel upon a segmental track-way, GrA

H, so that the cradle does not simply tilt, but is carried ibrward and backward on said track-way, and is v much more easily n'lanaged than if '1t-moved upon a pivot.

aided by intermediate gearing, if the cradle is to be operated by hand-power.

We therefore employ the racks lk., which are secured to each side of the cradle; and suitable pinions, oper- 'ated by the. crank J, are secured in'beaxings upon the truss-traine, which supports the` segments G H. By turning the crank J, by hand or other power, the cradle is run forward upon the curved track Gr H, until the car assumes the position 'shown in fig.A 2, when the gate I mar be opened for the exit of the grain, and, when the car has been emptied, a reverse motion of the crank and pinion restores the cradle to its original position. y

When the eradle is in position to make the trackway continuons, as in iig. l, the. swing-braces a a, or

equivalent devices, are moved forward, so that their tops eomebeneath ther ends of the said pieces B, and prevent the cradle from sinking at that end under a car that is passing along the track.

In order to hold and support alcar while upon the tilting-cradle, and keep it from running forward as the alents, are attac-hed to the track-way, and their free ends are raised up, so as to engage with some convenient part of the car or one of its trucks, as shown in iig. 2.

.In the above description, we have set forth a very simple plan iol-carrying our invention into effect.- The details of its-construction maybe very greatly varied, without in any degree changing the nature of the iuvention,and it may he applied to the unloading ofcars, wagons, or other vehicles, and they may be made to tilt sideways by a proper arrangement of theeradle and segmental track, if, from convenience or any other reason, `it maybe desirable. y

In place of trucks, smooth shoes may be employed sometimes, and, in that case, they maybe regarded as the full equivalents of the trucks. y

vHaving described our invention,

'What we claim as new, is-

l. A carriage or cradle, constructed in the roadway, v

and resting upon trucks'or shoes, and travelling upon a segmental track, snhstantiall,Y as described,.and for the purpose set forth.

2. Thearrangement of the cradle, trucks E and F, and segmental track G H, when constructed as described.

3, The swing-lnaees a. u and K K, or their equivalents, as,and for the purpose sctforth, in combination with the tilting-cradle and segmental track, as set forth.
